How to Grow Garlic in Pots and Care for It

by

Growing garlic in pots is a rewarding way to enjoy fresh, flavorful bulbs straight from your own patio, balcony, or garden space. With the right setup and care, you can harvest full heads of garlic in as little as eight to nine months from planting individual cloves.

Understanding Garlic’s Growth Cycle

Garlic takes time to mature. From the moment you plant a clove to the day you dig up a full bulb, expect around eight to nine months of growth. This slow process rewards you with high-quality garlic that is fresher and more aromatic than most store-bought options.

Planting Garlic in Pots

For the best results, plant garlic in the fall. This timing allows the cloves to establish strong roots before winter and to develop larger bulbs by the following summer.

  1. Choose the cloves – Select large, healthy cloves from a fresh garlic head. Avoid peeling them, as the papery skin helps protect against disease.
  2. Prepare the soil – Use a mix of quality potting soil and compost in a ratio of 3:1 for optimal drainage and nutrients.
  3. Plant with proper spacing – Place each clove with the pointed end facing up, spacing them about 5–10 cm (2–4 inches) apart. Cover them with soil so they are around 2–3 cm (1 inch) deep.

Choosing the Right Pots

Garlic grows best in containers that are at least 8 inches deep. You can use plastic, ceramic, or stone pots, as long as they have excellent drainage holes to prevent waterlogging. Deeper pots also allow for better root development and larger bulbs.

Caring for Garlic Through the Seasons

  • Watering – Garlic needs consistent moisture, especially during winter and spring. The soil should be kept damp but never soggy.
  • Mulching – Apply a 5 cm (2 inch) layer of organic mulch, such as straw or shredded leaves, to protect bulbs from cold temperatures and retain moisture.
  • Sunlight – Place pots in a sunny spot, ideally where they receive 6–8 hours of direct sunlight daily.
  • Winter protection – In colder climates, move pots to a sheltered area to avoid freezing damage, or wrap containers in insulating material.

Harvesting Garlic

Garlic is ready to harvest in early summer when about half of the leaves have turned yellow. Use a garden fork or small trowel to gently lift the bulbs from the soil. Avoid pulling them by the stems, as this can cause damage.

After harvesting, cure the garlic by laying the bulbs in a dry, airy place for two to three weeks. Once fully dried, trim the roots and stems, then store in a cool, dark, and well-ventilated location.

Additional Tips for Success

  • Avoid overwatering in late spring, as too much moisture can cause rot.
  • Rotate garlic planting locations each year to reduce the risk of soil-borne diseases.
  • Use a slow-release organic fertilizer in early spring to boost growth.

FAQs About Growing Garlic in Pots

1. Can I grow garlic indoors year-round?
Yes, but it requires a sunny windowsill or grow lights to provide at least 6 hours of light daily.

2. How many cloves can I plant in one pot?
This depends on pot size. An average 12-inch pot can hold about 6–8 cloves spaced properly.

3. Should I remove the flower stalks?
Yes. Cut off the scapes when they appear to encourage the plant to focus on bulb development rather than seed production.

4. Can I plant supermarket garlic?
While possible, store-bought garlic may be treated with growth inhibitors. Seed garlic from a reputable supplier is recommended for better results.

5. How long does garlic last after harvesting?
Properly cured and stored garlic can last 6–9 months.
